OIL-CUP.

Specification of Letters Patent.

Patented July 23, 1907.

Application filed June 22,1906. Serial No. 322.966.

To all whom it may concern:

Be it known that I, JAMES H. DAVIS, a citizen of the United States, anda resident of Portland, Multnomah county, State of Oregon, have inventeda new and use-.

ful Improvement in Oil-Cups, of which the following is a specification,reference being had to the accom panying drawings as constituting a partthereof.

My invention relates to oil cups which are designed to feed lubricant tocrank pins, or movable bearings of an engine, and has for its object toprovide a cup which is especially adapted to contain semi-solid or solidlubricant, or what is commonly known as hard oil,

' and to feed such lubricant .to the bearings in a controllable anddependable manner.

I attain my object by the devices shown in the drawings and hereinafterdescribed.

In the drawings, Figure 1 represents in its right half an elevation ofmy oil cup installed as in practice, and the left half thereof is asection; and Fig. 2 is a detail, partly in section, of what I term thevibratable pin.

The letters designate the parts referred to.

My invention comprises a hollow cylindrical body a, the head of which ismade with a threaded aperture b, in which to receive an adjustment-screwcl. On the shank of such adjustment-screw is placed a lock-nut e, sothat when the adjustment has been made, as hereinafter described, thescrewd may be locked against turning up or down because of thevibrations of the engine. The bottom 01 the body a, is made with a neckf, having a threaded reduced portion g, arranged to be inserted in thethreaded hole of the bearing h, as usual; and such bottom part isprovided with a vertical aperture 11. In the latter is inserted theshank of a vibratable pin j, comprising a shank and a hollow head It.The shank of such pin j, is made square in cross section, or at allevents, with flat faces, so as to leave a passage-Way between such facesand the wall of the aperture 1', in the base of the cup, for thelubricant to pass through to the bearings. The hollow head 70 is madewith a removable plug Z, and in such hollow head is placed a ball m,which ball constitutes a loose weight, and during the vibrations of theengine contributing the energy imparted to it by the motion of'the crankdisk, for example, toward inducing a vibratory, or upand-down motion ofthe vibratable pin, in the aperture 1'. Within the body a, are placedtwo or more balls n, representing loose weights, which during'the run ofthe engine, pound the upper surface of 'the lubricant and help to feedthe same to the hearing. The vibrations of the pin j, causes a steadyfeed of lubricant to the bearings and the up-and-down motion or strokeof the pin is controlled by the adjustment of the screw (1. It is thusapparent, that my device taken as a whole, constitutes what may betermed a ball and pin feed oil cup.

The advantage of my device is that it does not feed lubricant while theengine is at rest, but as soon as the engine starts up, the vibratablepin j feeds a small quantity of the lubricant with each up-and-downmotion thereof.

I claim:

1. The combination with an oil-cup, the base of which is made with avertical central aperture, of a vibration pin, the walls of the apertureand the faces of the shank of such pin being adapted to leave apassage-way for the lubricant between them; said pin being made with ahollow head a loosewveight in such hollow head, and adjustment means inthe head of the cup adapted to control the vibrations of the pin.

2. The combination with an oil-cup, the base of which is made with avertical central aperture, of a vibration pin, contained in suchaperture, the walls of the aperture and the faces of the shank of suchpin being adapted to leave a passage-way for the lubricant between them;said pin being made with a hollow head; a removable plug in such head,so that a loose weight may be inserted therein; loose weights in thebody of the cup, and adjustment means in the head of the cup adapted tocontrol the vibrations of the pin.

3. An oil-cup comprising a hollow body, the base of which is made with avertical central aperture, 2. vibratable pin contained in such aperture,the walls of the latter and the faces of the shank of the pin beingrelatively formed, so as to leave a passageway for the lubricant betweenthem; said pin being made with a hollow head; a loose weight containedin such head; a centrally apertured cap removably afiixed in the head ofthe cup, :1 set-screw, in the aperture of the cap, whereby to controlthe vibrations of the pin; and a loclcnut on the shank of the setscrew.
